prometheus.service file as follows:

After=network-online.target

[Service]
User=root
Restart=on-failure

#Change this line if you download the 
#Prometheus on different path user

ExecStart=~/prometheus/prometheus --storage.tsdb.path=/var/lib/prometheus/data/ --web.external-url=http://myurl.com:9090

[Install]
WantedBy=multi-user.target

You need to use an absolute path in prometheus.service file:

ExecStart=/xxx/yyy/zzz/prometheus/prometheus ...
